[0002] Bearings are an important component in contemporary mechanical equipment. They are used to determine the relative motion position of the rotating shaft and other parts, and they play a supporting or guiding role. Its main function is to support the mechanical rotating body to reduce the mechanical load friction coefficient of the equipment during the transmission process. The bearing cage, also known as the bearing retainer, refers to the bearing part that partially wraps all or part of the balls and moves with them. During operation, the main contact part of the steel ball is the hole wall of the ball pocket. There are many types of bearing cages with various functions, which can meet the performance requirements of the transmission mechanisms of various mechanical equipment.

DETAILED DESCRIPTION

[0034] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0035] like Figure 1 - Figure 3 As shown, the new energy vehicle wheel hub bearing retainer provided in this embodiment is a new energy vehicle wheel hub bearing retainer, comprising a bearing 2 installed on a vehicle wheel hub 1 and a retainer 3 installed on the bearing 2, the retainer 3 comprising a retainer body 301 and a sealing cover plate 304, the retainer body 301 is provided with a ball groove 302, a pocket beam 303 and an inspection groove 311, and the retainer body 301 is provided with a cavity 305; a plurality of ball grooves 302 and a plurality of pocket beams 303 are provided, the retainer body 301 is annular in shape, and a plurality of ball grooves 302 and a plurality of pocket beams 303 are spaced apart and arranged on the retainer body 301.

[0036] In this embodiment, Figure 2 - Figure 4 As shown, a sealing cover plate 304 is detachably mounted on the bottom side of the holder body 301, and an inspection groove 311 is arranged on the bottom side of the holder body 301 and is shielded by the sealing cover plate 304. The sealing cover plate 304 is bolted to the bottom side of the holder body 301.

[0037] To improve the strength of the retainer 3, Fig. 9 As shown, a reinforcement structure 4 is provided in the cavity 305, and the reinforcement structure 4 includes a first reinforcement rib 401 and a second reinforcement rib 402, which are arranged in a cross shape, and the first reinforcement rib 401 and the second reinforcement rib 402 are fixedly connected to the inner wall of the cavity 305. A stabilizing frame 5 is detachably installed on the inner side of the pocket beam 303, and mounting holes 51 are provided inside the pocket beam 303 and the stabilizing frame 5. The hollow structure is provided in the retaining frame body 301, which not only reduces the weight but also enhances the strength and rigidity of the structure. The cross-shaped first reinforcement rib 401 and the second reinforcement rib 402 further enhance the bearing capacity of the retaining frame body 301, so that it can adapt to various complex working conditions. The installation of the stabilizing frame 5 further enhances the firmness of the retainer 3, so that the wheel hub of the new energy vehicle can be better used.

[0038] Specifically, the number of the first reinforcing ribs 401 and the second reinforcing ribs 402 is not limited and is set according to the size of the cage body 301. The hollow design and the cross-shaped reinforcing ribs help reduce the weight of the cage body 301 while maintaining sufficient structural strength to cope with various forces and vibrations when the bearing 2 is running.

[0039] In this embodiment, if Figure 2 - Figure 6As shown, the inside of the retainer body 301 is provided with an oil delivery hole 306 connected with the ball groove 302 and the cavity 305, and a sealing plug 307 is arranged in the oil delivery hole 306, and a sealing structure 310 extending to the inside of the cavity 305 is installed on the side of the sealing plug 307 close to the oil delivery hole 306, and the sealing structure 310 includes a push rod 3101, a spring 3102, an extension rod 3104, a gasket 3105 and a pressure block 3106; the outer surface of the sealing plug 307 is sleeved with a first sealing gasket 3071, and the outer diameter of the sealing plug 307 is adapted to the inner diameter of the oil delivery hole 306, and the installation of the first sealing gasket 3071 is matched to achieve the sealing of the oil delivery hole 306. The top side of the spring 3102 is fixed to the lower surface of the sealing plug 307, the bottom side of the spring 3102 is fixed to the inner wall of the cavity 305, and the spring 3102 surrounds the outer surface of the push rod 3101. By installing the spring 3102 , the elastic setting of the sealing plug 307 is achieved, so that it can maintain the sealing of the oil delivery hole 306 .

[0040] In this embodiment, one end of the push rod 3101 away from the sealing plug 307 passes through the interior of the retaining frame 301 and extends into the inspection groove 311. A second sealing gasket 3103 for sealing is fixedly installed on the outer surface of the retaining frame 301 near the bottom end of the push rod 3101 to improve the sealing of the cavity 305.

[0041] Specifically, the extension rod 3104 is threadedly connected to the push rod 3101, the gasket 3105 and the pressure block 3106 are both hollow inside, the gasket 3105 is threadedly connected to the extension rod 3104, the pressure block 3106 is fixedly installed on the upper surface of the gasket 3105 and sleeved on the outside of the extension rod 3104. The pressure block 3106 is circular in shape and hollow inside, and a micro pressure sensor is installed inside the pressure block 3106. Through the installation of the micro pressure sensor, the sealing plug 307 can be monitored. When the sealing plug 307 reciprocates, it will drive the push rod 3101 to expand and contract. At this time, the pressure block 3106 will contact the outer surface of the retaining frame 301, and the impact during the contact can be transmitted to the monitoring device through the micro pressure sensor, so as to detect the bearing 2 in time. The micro pressure sensor belongs to the conventional technology known to the public in the prior art, so the specific structure and working principle will not be described in detail in this article.

[0042] Among them, by installing the extension rod 3104, the installation position of the pressure block 3106 can be adjusted.

[0043] like Figure 3 and Figure 7As shown, a lubricating pad 308 used in conjunction with the oil delivery hole 306 is detachably installed inside the ball groove 302, and the lubricating pad 308 includes a bottom pad 3081, a top pad 3082, and a feeler rod 3083. The feeler rod 3083 is fixedly installed on one side of the lubricating pad 308 close to the ball groove 302, and the other end of the feeler rod 3083 abuts against the pressure block 3106. An oil outlet hole 309 is provided inside the top pad 3082, and the shape of the oil outlet hole 309 is set small. The feeler rod 3083 moves and pushes the pressure block 3106 through the deformation of the lubricating pad 308. By injecting lubricating oil into the cavity 305, the design of the bearing ball groove 302 and the oil delivery hole 306 allows the lubricating pad 308 to be deformed by shaking when the bearing 2 lacks lubrication. The touch rod 3083 is displaced by the deformation of the lubricating pad 308 to push the pressure block 3106 and then open the oil delivery hole 306, thereby realizing automatic lubrication of the bearing 2. At the same time, the setting of the bottom pad 3081 and the top pad 3082 makes the lubrication process more precise and controllable. A layer of the bottom pad 3081 close to the oil delivery hole 306 is responsible for absorbing oil and opening the oil delivery hole 306 by deformation. The outer top pad 3082 is against the bearing 2, and the lubricating oil is evenly delivered to the bearing surface through the smaller oil outlet hole 309.

[0044] Specifically, the bottom pad 3081 is fixedly connected to the top pad 3082. Through the arrangement of the bottom pad 3081 and the top pad 3082, the design of the two-layer lubricating pad 308 enables the lubricating oil to be more accurately delivered to the surface of the bearing 2, reducing the waste of lubricating oil and improving the lubrication efficiency. Not only does it enhance the sealing performance, but the outer top pad 3082 is against the bearing and a smaller oil outlet hole 309 is provided, which helps to prevent the lubricating oil from leaking when it is not needed, enhancing the sealing performance and protecting the bearing 2. By precisely controlling the delivery of the lubricating oil, the two-layer lubricating pad 308 can better protect the bearing from wear and damage and extend the service life of the bearing. The shape of the lubricating pad 308 is adapted to the inner side of the ball groove 302. For the material selection of the two-layer lubricating pad 308, the following are recommended: The bottom pad 3081 close to the oil delivery hole 306: This layer of lubricating pad 308 needs to have good elasticity and wear resistance so that it can be deformed in time and open the oil delivery hole 306 when the bearing shakes. At the same time, it also needs to have a certain oil absorption capacity so that the lubricating oil can be sucked in and transported to the bearing surface. Therefore, it is recommended to use rubber materials or polymer materials, such as polyamide (nylon), etc. Outer top pad 3082: The outer lubricating pad 308 needs to have good sealing and wear resistance so that it can prevent the lubricating oil from leaking when it is against the bearing and protect the bearing from wear. At the same time, it also needs to have a certain elasticity so that it can adapt to slight deformation when the bearing is running. Therefore, it is recommended to use rubber materials, polymer materials or composite materials, etc., which can reduce the impact on the operation of the bearing.

[0045] In summary, the setting of the lubricating pad 308 and its elastic characteristics are the key to this mechanism, which can sense the vibration of the bearing and respond. Sealing: The elastically installed sealing plug 307 in the oil delivery hole 306 helps to keep the oil delivery hole 306 closed when lubrication is not required to prevent lubricating oil leakage. The oil delivery hole 306 is opened and closed by the deformation of the lubricating pad 308, and the vibration caused by the lack of lubrication of the bearing is used to deform the lubricating pad 308, so as to open the oil delivery hole 306 and achieve lubrication of the bearing. This design cleverly uses the movement characteristics of the bearing itself to achieve lubrication, reducing manual intervention and the complexity of the lubrication system. This method also has good practicality. Automatic lubrication function: This design can automatically open the oil delivery hole 306 for lubrication when the bearing lacks lubrication, avoiding bearing damage and failure caused by insufficient lubrication, improving the reliability and durability of the bearing, and easy maintenance: Because the design has an automatic lubrication function, it reduces the frequency and difficulty of manual lubrication, and reduces maintenance costs and time. Strong adaptability: This design is suitable for various types and specifications of automobile wheel hub bearings, can be widely used in different types of vehicles, and has wide applicability.

[0046] like Figure 1 - Fig. 9 As shown, the principle of the new energy vehicle wheel hub bearing retainer provided in this embodiment is as follows:

[0047] When the present invention is used, lubricating oil is injected into the cavity 305. The design of the bearing ball groove 302 and the oil delivery hole 306 allows the lubricating pad 308 to be deformed by shaking when the bearing lacks lubrication. The touch rod 3083 is displaced by the deformation of the lubricating pad 308 to push the pressure block 3106 and then open the oil delivery hole 306, thereby realizing automatic lubrication of the bearing. At the same time, the arrangement of the bottom pad 3081 and the top pad 3082 makes the lubrication process more precise and controllable. A layer of the bottom pad 3081 close to the oil delivery hole 306 is responsible for absorbing oil and opening the oil delivery hole 306 by deformation. The outer top pad 3082 is against the bearing and the lubricating oil is evenly delivered to the bearing surface through the smaller oil outlet hole 309.
